Abstract
A green synthesis of pure zinc oxide and silver-doped zinc oxide nanoparticles (ZnO and Ag-ZnO NPs) is reported. This eco-friendly method utilizes tobacco leaf aqueous extract as a reducing and stabilizing agent, combined with a hydrothermal process at 120°C for 6 hours to control nanoparticle formation. The study aimed to synthesize, characterize, and evaluate the antimicrobial...
In this study, first principles calculations are employed to investigate the structural, electronic, and optical properties of (Ni, Zn)xCo1−xS in its tetragonal phase. The optimized lattice parameters and negative defect formation energies confirm structural integrity and thermodynamic stability across doping levels. The calculations are performed using both the GGA and the HSE06 hybrid...
Abstract:
The catalysts with metal particles as active sites play an important role for the understanding of hydrogen reaction mechanism for rational design of electrocatalysts. Recently, the application of metal organic frameworks (MOFs) in electrochemical hydrogen production has significantly increased. Here, a molybdenum-copper metal-organic framework (Mo-Cu MOF) was prepared by a simple...
1- Introduction
New instruments have been employed for spectroscopic studies of gaseous astrophysical environments using synchrotron photoabsorption in the soft X-ray range (0.1–2 keV) at the Elettra Laboratory in Trieste, Italy.
The first instrument used in this study is the Electron Beam Ion Trap (EBIT) [1]. The second is a newly developed setup called the OctoIonGuide (OIG), which was...
